No parameters support in "create user"?

Hi list,

When I try to create a user using the "create user" SQL command, where 
the command is being executed using the PQexecParams function from 
libpq, and the username and password are passed as "text" (oid 0x19) 
parameters (binary), I get a syntax error. The command I'm doing is:

create user $1 with encrypted password $2

Any idea why this is not working? Is it supposed to work? Trying to pass 
only the password as a parameter does not work either.
